In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
The embodiment of the application provides a door lock control device, and the door lock control device can comprise: the device comprises a control unit, a driving unit, a transmission mechanism and a push rod; wherein, the control unit is connected with the driving unit and is used for controlling the action of the driving unit; the transmission mechanism is connected with the driving unit and the push rod and is used for transmitting the action of the driving unit to the push rod; the push rod is used for pushing a handle of the door lock controlled by the door lock control device. Wherein, the handle of above-mentioned lock can contain in the ordinary lock of installing on the door, like this, the control to the handle that this ordinary lock includes can be realized to the lock controlling means that this application example provided, and then realizes unblanking and locking to ordinary lock, consequently, this lock controlling means can cooperate with ordinary lock phase in order to realize intelligent lock's function.
In practical application, the user can trigger the door lock control device in an intelligent unlocking mode such as remote unlocking, weChat unlocking or Bluetooth unlocking and the like so as to realize the unlocking and/or locking of the ordinary door lock and realize the function of an intelligent door lock of the ordinary door lock. For example, the user may send an unlocking request to the control unit in an intelligent unlocking manner such as remote unlocking, wechat unlocking, or bluetooth unlocking, so that the control unit drives the driving unit to operate.
In an alternative embodiment of the present application, the transmission mechanism may include a gear and a rack, the gear is connected to the driving unit, the gear is abutted against the rack, and the push rod is connected to the rack. Thus, the driving unit can drive the gear to rotate under the control of the control unit, so that the gear is meshed with the rack to drive the push rod to move, and the push rod pushes the handle of the door lock controlled by the door lock control device.
In an optional embodiment of the present application, the control unit may provide a signal capable of driving the gear to rotate in a forward direction to the driving unit in response to an unlocking request from a user, where the forward rotation of the gear indicates a rotation in a direction that enables the push rod to push the handle of the door lock to open the door lock. Optionally, the forward rotation may be clockwise rotation or counterclockwise rotation, so that the push rod pushes the handle of the door lock to rotate by the forward rotation of the gear, thereby opening the door lock. Optionally, the control unit may include a processor. In some embodiments, a processor may be implemented using general-purpose or custom circuits, such as an Application Specific Integrated Circuit (ASIC) or a Field Programmable Gate Array (FPGA).
In another optional embodiment of the present application, the control unit may further include a detection module, where the detection module may be configured to detect an operating current of the driving unit, and when the operating current meets a preset condition, the control unit may control the driving unit to stop operating.
Since the forward rotation is stopped when the handle of the door lock has rotated to the end position of the rotation of the door lock handle in the case of opening the door lock, the reaction force of the handle of the door lock against the driving unit is suddenly increased, and accordingly, the increase of the resistance force causes the operating current of the driving unit to be increased. Therefore, the working current of the driving unit can be used as the basis for judging whether the door lock is opened or not. In practical application, a preset condition may be set, and when it is detected that the working current of the driving unit meets the preset condition, the door lock may be considered to be in an open state, so that the control unit may control the driving unit to stop working, so as to avoid damage to the door lock or the door lock control device due to a large reaction force.
In practical applications, the preset conditions may include: the increase in the operating current per unit time exceeds a first threshold, e.g., if the operating current increases by 0.5 amperes per millisecond, the operating current may be considered to meet a preset condition. It is understood that the preset conditions may be determined by those skilled in the art according to the actual application requirements, for example, the preset conditions may further include: the increase rate of the operating current in unit time exceeds the second threshold, or the operating current exceeds the third threshold, and the like, and the specific preset condition is not limited in the embodiment of the present application.
In yet another optional embodiment of the present application, the control unit may further include a timing module, and after the driving unit stops working for a preset time, the control unit may provide a signal capable of driving the gear to rotate in a reverse direction to the driving unit, where the reverse rotation of the gear refers to a rotation in a direction that the push rod returns to the initial position. In this embodiment, the reverse rotation may be counterclockwise rotation or clockwise rotation, and the rotation of the gear in the direction may enable the push rod to rotate until returning to the initial position, so as to rotate the handle of the door lock through the rotation of the push rod, and further lock the door lock.

In practical applications, the preset time may be used to reflect an interval from the unlocking state to the locking state of the door lock. It is understood that the preset time can be determined by those skilled in the art according to the actual application requirement. For example, to improve safety, the preset time may be a small value, such as 3 seconds or 5 seconds. In addition, the user may set the preset time according to a requirement of the user, for example, in the case that a home includes multiple users, the user may wait for other users to get home after unlocking the lock, and then lock the door lock, and the preset time may be a larger value, such as 1 hour, and it is understood that the specific preset time is not limited in the embodiment of the present application.
In practical applications, the door lock control unit may further include: the request receiving unit may be configured to receive an unlocking request. Optionally, the request receiving unit may include: at least one of a keyboard, a fingerprint recognizer, and a Near Field Communication (NFC) receiver, the specific request receiving unit is not limited in the embodiments of the present application. After receiving the unlocking request of the user through the request receiving unit, the control unit can judge whether the unlocking request is matched with a preset unlocking request or not so as to authenticate whether the identity of the user is legal or not, if so, the user can be considered as a legal user, and then the drive unit is controlled to drive the transmission mechanism to act, so that the rotation of the door lock handle is realized, and the unlocking or locking of the door lock is realized through the rotation of the door lock handle. In the embodiment of the application, the authentication of the user identity is realized through the matching between the unlocking request and the preset unlocking request, so that the use safety of the door lock control device can be improved.
In an application example of the present application, if an NFC receiver is provided on the door lock control device, after an unlocking request sent by a user through a terminal device is received by the NFC receiver, the control unit may match the unlocking request with a preset unlocking request, and if the matching is successful, may control the driving unit to drive the transmission mechanism to act, so as to implement opening and locking of the door lock.
Alternatively, the driving unit may include: a drive motor and a turbo-reduction motor; wherein the drive motor is capable of rotating in a forward direction or a reverse direction, and the turbo-reduction motor is connected between the drive motor and the gear to reduce a rotational speed of the gear to be lower than a rotational speed of the drive motor. The driving motor can be used for converting electric energy into kinetic energy, and the torque is smaller due to the higher rotating speed output by the driving motor; the turbine speed reducing motor set between the driving motor and the gear can reduce the rotation speed of the driving motor and increase the output torque of the driving motor to provide proper rotation speed and torque to the gear to make the rotation speed of the gear lower than that of the driving motor.
Further, since the worm gear reducer has self-locking properties, the torque transmission direction between the worm gear reducer and the gear may be unidirectional, that is, the torque transmission direction between the worm gear reducer and the gear may be a direction from the worm gear reducer motor to the gear. The turbine speed reducer has the characteristic of self-locking, after the push rod drives the door lock handle to rotate to open the door lock, the reaction force of the door lock handle on the push rod can prevent the gear from rotating, so that the gear can keep a rotation stop state until the driving unit drives the gear to rotate reversely after the preset time.

For example, if the positive pole of the power supply is connected to the positive pole of the driving motor and the negative pole of the power supply is connected to the negative pole of the driving motor, the driving motor rotates forward; alternatively, the drive motor is reversed when the negative pole of the power source is connected to the positive pole of the drive motor and the positive pole of the power source is connected to the negative pole of the drive motor. In the process of controlling the door lock, the control unit may control the positive electrode of the power supply to be connected to the positive electrode of the driving motor and the negative electrode of the power supply to be connected to the negative electrode of the driving motor to drive the driving motor to rotate in the forward direction, and the gear is driven to rotate in the forward direction through the forward rotation of the driving motor, so as to drive the push rod to rotate from the initial position, so as to push the handle of the door lock to rotate through the push rod, thereby opening the door lock; after the door lock is opened, the control unit may control the power supply to stop supplying power to the driving motor, and the driving motor stops rotating; after the driving motor stops rotating for a preset time, the control unit can control the positive pole of the power supply to be connected with the negative pole of the driving motor, the negative pole of the power supply is connected with the positive pole of the driving motor to drive the driving motor to rotate in the reverse direction, the gear is driven to rotate in the reverse direction through the reverse rotation of the driving motor, the push rod is driven to rotate until the push rod returns to the initial position, the door lock handle is rotated through the rotation of the push rod, and then the door lock is locked.
Optionally, the movable track of the push rod may be arc-shaped, and in practical applications, the arc-shaped movable track may be adapted to a rotation track of the door lock handle, so that wear of the movable track may be reduced in a process of the push rod pushing the door lock handle to rotate.
Optionally, the door lock control device may further include a driving unit housing, and the driving unit housing may include: the upper shell and the lower shell are matched to form a cavity part, and the cavity part can be used for covering and supporting the driving unit, so that foreign matters such as external dust can be prevented from entering the driving unit.
Optionally, the door lock control device may further include a housing, and the housing may include a curved surface disposed at a bottom of the door lock control device and a curved surface disposed at a side of the door lock control device. The material of above-mentioned shell can be materials such as plastic, panel beating, and this application embodiment does not put the restriction to the material of above-mentioned casing. The shell is used for supporting the door lock control device, and in practical application, the shell can be fixed near a common door lock installed on a door in a screw connection or sticking connection mode.
In practical applications, the request receiving unit may be disposed outside the door, connected to the control unit disposed inside the door by a wire or a wireless connection, and configured to send the unlocking request received by the request receiving unit to the control unit.
For example, if the unlock request includes: the request receiving unit can receive an unlocking password input by a user through the keyboard and send the unlocking password to the control unit, then the control unit can judge whether the unlocking password is matched with a preset unlocking password or not after receiving the unlocking password of the user, if so, the drive unit is controlled to drive the gear to rotate in the forward direction, and then the push rod is driven to rotate in the forward direction from an initial position, so that the rotation of the door lock handle is realized through the rotation of the push rod, and the opening of the door lock is realized; the detection module on the control unit detects the working current on the driving unit, and when the working current meets the preset condition, the driving unit is controlled to stop working; after the driving unit stops working for a preset time, the control unit provides a signal capable of driving the gear to rotate reversely to the driving unit, so that the gear is driven to rotate reversely, the push rod is driven to rotate until the push rod returns to the initial position, the door lock handle is rotated through rotation of the push rod, and locking of the door lock is achieved.
Therefore, because the door lock control device is provided with the request receiving unit, the request unit can be used for receiving an unlocking request of a user, the user can send the unlocking request to the door lock control device in a mode of inputting a password, inputting a fingerprint or swiping a card and the like, the door lock control device can control a common door lock to realize the function of an intelligent door lock according to the unlocking request, in practical application, the user can select the request receiving unit as required, the request receiving unit is added to the door lock control, the types of the unlocking requests which can be supported by the door lock control device can be increased, the user can conveniently input the unlocking requests in various modes, the user identity is authenticated through the unlocking request so as to improve the safety of door lock control, and the user experience is greatly improved.
